Unity Analysis on Direction Finding Models for Monopulse Radar and Electronic Reconnaissance

对电磁信号的来波方向进行测量是雷达与电子侦察这两个不同工程领域所共同关注的相同应用。针对测向问题,分别通过比幅单脉冲雷达与电子侦察比幅测向模型的对比分析,以及比相单脉冲雷达与电子侦察中单基线干涉仪测向模型的对比分析,揭示了二者在数学模型上的统一性,展示了二者测量结果之间的一一对应关系。在此基础上,概要阐述了上述统一的测向模型在推进雷达与电子战设备的一体化发展,对电子侦察的干扰样式借鉴推广,以及单脉冲雷达工作带宽拓展等方面的应用,从而为无线电测向理论的创新性应用研究提供了重要参考。

The direction finding for electromagnetic signals is the same application for radar and electronic reconnaissance, which belong to two different engineering fields. In this paper, the amplitude comparison direction finding models for monopulse radar and electronic reconnaissance equipment are compared and analyzed. The phase comparison direction finding models for monopulse radar and single baseline interferometer in electronic reconnaissance are compared and analyzed. The comparison and analyses reveal unity of direction finding models in both fields in terms of mathematical models and one-to-one correspondences between their measurement results. Then applications of the unified direction finding models in promoting the integrated development of radar and electronic warfare equipment, learning and popularizing patterns of jamming on electronic reconnaissance equipment, and expanding working bandwidth of monopulse radar are briefly described. This paper provides an important reference for the innovative application research of radio direction finding theory.
